What is the universal (world wide) understanding behind degaussing harddisks?
Good evening from Singapore! The foremost question which I want to ask is, what is the universal (world wide) understanding behind degaussing hard drives? I work for No Secrets Agency (NSA) Pte Ltd (fictitious company name used). My sales manager Edward Joseph Snowden (fictitious individual name used) had *promised* our customer Leave Me in the Lurch (S) Pte Ltd (fictitious company name used) that we would "DEGAUSS" their h...

OT: hardware: sanitizing a dead SSD?
Anyone have any clues about how to sanitize a dead SSD? We haven't had it yet, but we're sure it's coming. Esp. since I'm a federal contractor, a dead disk gets deGaussed, but what the hell do you do with a SSD?

X100P Burnouts
...the server, approximately 3 feet in length. Now here is where things get interesting... That 3 foot cable run passes behind a 21" monitor that was connected to the server. When the line tests showed everything OK, I decided the monitor might be a long shot but I could understand how the degaussing coil coil could possibly induce a surge on the phone line if the monitor was somehow degaussing nightly, so I unplugged the monitor's power cable and left everything else as it was. So far so good. X100p #4 is still working this morning, so it looks like the problem is solved. Hope th...

For disks that work, shred or DBAN is what we use. For dead disks, we do the paperwork, and get them deGaussed. SSD's are a brand new issue. We haven't had to deal with them yet, but it's surely coming, so we might as well figure it out now. mark

Utility to zero unused blocks on disk
DBAN is obsolete. NIST 800-88 for some time now says to use secure erase or enhanced security erase or crypto erase if supported. Other options do not erase data in remapped sectors. Chris Murphy

...wear factor in highly as to whether or not data can be readily recovered, and to a greater factor, if hdd is mounted vertical or horizontal. if one wishes, as mentioned in two of post, "sledge hammer" and "hydraulic wedge", are good ways. much better, and more assured is 'degaussing' disk platters, even which will leave a small bias. best way, of insuring data removal is to scrape disks clean of coating, or to burn off coating. i have used latter. -- peace out. in a world with out fences, who needs gates. tc.hago. g .

zfs eradication
Hi, I was discussing the common practice of disk eradication used by many firms for security. I was thinking this may be a useful feature of ZFS to have an option to eradicate data as its removed, meaning after the last reference/snapshot is done and a block is freed, then write the eradication patterns back to the removed blocks. By any chance, has this been discussed or considered before?
